Bettas only live for a week! (from my friend in third grade)
1fish2fish-I have heard the same thing about goldfish! It's just not true!
That bettas fight to the death in the rivers. (They won't if they have space to retreat)
I head from someone when I first started buying bettas that female bettas were really ugly and I would never want to buy one if I ever saw them 0_o how untrue is that...they are beautiful! I have more females than males.
